THOMAS SHERRY, OF NEENAH, VISGONSIN.

CARRIAGE-AXLE CUTTER.

SPECIFICATION forming part of Letters Patent No. 280,678, dated July 3, 1883.

' Application filed December 4, 1882. (No model.)

To (LZZ whom it may concern.-

Be it known that I, THOMAS SHERRY, a citizen of the United States, residing at the city of Neenah, in thccounty of Winnebago and State of Wisconsin, have invented a new and useful Improvement in Carriage-Axle Cutters, of which the following is a specification.

My invention relates to improvements in carriage-axle cutters, in which rotary cutters, in connection with appropriate devices for securing the same to the axle and mechanism for feeding the cutters to the work to be performed, are employed to shorten the axles as their shoulders and the boxes of their wheels become worn, thereby obviating their excessive longitudinal movement, and dispensing with the washers usually employed for that purpose.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a side elevation of the entire machine as applied to a carriage-axle for operation thereon. Fig. '2 is a top view ofthe clamping mechanism, at the left of the line 0c of Fig. 1, as applied to the axle for operation. Fig. 3 is a vertical section on the line as w of the same. Fig. 4c is a vertical section on the line 9 3 Fig. 1, showing the cutting-tools in their application and Fig. is a vertical section on the line z 2-, showing the feeding device.

Similar'letters of reference indicate corre sponding parts in the several views.

A represents a carriage-axle; E E,the clamps, by which is secured thereto the cutting mechanism; A A, the bolts by which it is secured; O, a lug upon said clamps; B, a dog applied to the axle and jsaid lug. L L'L L represent round rods connecting plates F and I. K is a plate sliding loosely upon said rods. H H H H are bolts securing plate F to clamps E E. J is the crank-shaft, having the cutting-tools p and g at its extremity, and revolving iii plates land K. J is the crank applied to shaft J. M M represent pinions, which are threaded internally, and are mounted upon the thread ed studs in m. 0 is a pin or stud projecting from the'crank-shaft J, and actuating the pinions The clamping device is placed upon the axle, as shown in Figs. 1 and 2, and secured thereto" by the bolts A A, and also, when necessary, by the application of the dog B over the lug LC and back of the collar D upon the axle.

The clamps E E are separate from the plate F, and secured thereto by bolts H H, said plate and the cutting mechanism connected with it by the bolts L L L L being adjustable in a horizo'ntal plane with the axle by said bolts moving in the slots 71 h. Said clamps E E are tapering in the angular recess applied to the axle, corresponding with the taper of the axle, thus centering the plate F and the cutting mechanism connected thereto with the axle in a hori- -zontal plane. The plate F is connected with plate I by the bolts L L and nuts Z Z. The crank-shaft J revolves in said plate I, and also in plateK, in which it is prevented from longitudinal movement by the shoulder is, the washer 7c, and the pin k. The plate K is adapted for longitudinal movement upon the bolts L L. The pinions M M, through which pass the threaded studs m m, are threaded internally, one end of each stud being secured in plate K. The hubs of pinions M M are extended through plate I, upon the outside of which are collars n 01, thereby retaining the pinions by their shoulders upon one side and the collars out upon the other in their bearings in the plate I.

By revolving the shaft J, by means of the crank J, forward in the direction of the arrow, the pin 0 engages the teeth of pinions M M, revolving them upon the threaded studs m m,

J, carrying the cutters p q, longitudinally toward the axle and reducing its length, the cut The adjustment of the tools 1) q is accom- /plished by moving them in their grooved bed nearer to or farther from the center of the toolholder, in which they are secured by the bolts 1 2. This adjustment is made before the cutthereby forcing the plate K, and with it shaft ter 1) cutting off a portion of its shoulder and q its extremity until the desired length is'atti 11g ope 'ation commences, after which the cutting proceeds, while the cutting tool holder is feeding in alongitudinal direction, until the desired length is attained. The cutter (1 may be so adjusted as to remove the material to the center of the axle, or a part only of it, and the remainder can be removed with a cold-chisel. \Vhen the required length is attained, the cutting apparatus is removed, and the thread formed in the usual well-known manner.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
